Hi,

I have an ant task for creating schema which doesn't work. I get an exception:

[hibernatetool] Executing Hibernate Tool with a Standard Configuration
[hibernatetool] 1. task: hbm2ddl (Generates database schema)
[hibernatetool] SLF4J: Failed to load class "org.slf4j.impl.StaticLoggerBinder".
[hibernatetool] SLF4J: See http://www.slf4j.org/codes.html#StaticLoggerBinder for further details.

BUILD FAILED
java.lang.NoClassDefFoundError: org/slf4j/impl/StaticLoggerBinder
at org.slf4j.LoggerFactory.<clinit>(LoggerFactory.java:60)

I have slf4j from the hibernate dist in my lib directory.

My log4j.properties file:

log4j.appender.stdout=org.apache.log4j.ConsoleAppender
log4j.appender.stdout.Target=System.out
log4j.appender.stdout.layout=org.apache.log4j.PatternLayout
log4j.appender.stdout.layout.ConversionPattern=%d{ABSOLUTE} %5p %c{1}:%L - %m%n

log4j.appender.file=org.apache.log4j.FileAppender
log4j.appender.file.File=hibernate.log
log4j.appender.file.layout=org.apache.log4j.PatternLayout
log4j.appender.file.layout.ConversionPattern=%d{ABSOLUTE} %5p %c{1}:%L - %m%n

log4j.rootLogger=warn, file
log4j.logger.org.hibernate=debug, file
log4j.logger.org.hibernate.SQL=debug, file

My ant task:

<taskdef
name="hibernatetool"
classname="org.hibernate.tool.ant.HibernateToolTask"
classpathref="project.classpath"/>

<target name="createschema">

<hibernatetool destdir="${basedir}">
<classpath path="${build.dir}"/>

<configuration
configurationfile="${build.dir}/hibernate.cfg.xml"/>

<hbm2ddl
drop="true"
create="true"
export="true"/>
</hibernatetool>
</target>

Any ideas?
Thanks,
Andy

i encountered this error some time back - had to clean out jars and had to move to single version of hibernate, spring.
